- Derivation of velocity in nth Bohr orbit - Physics Forums
Homework Statement (a) Derive an expression for the electron's speed in the nth Bohr model (b) Prove that the orbit with highest speed is the n = 1 orbit,with v(1) = ke^2 h compare this with the speed of light , and comment on the validity of ignoring relativity (as we did) in
- Is velocity ever a scalar quantity? - Physics Forums
I thought velocity was always a vector quantity, one with both magnitude and direction When it came to the suvat equations, where v = final velocity, and u = initial velocity, I thought both of those were vector quantities, e g; v (final velocity) 112km hr North u (initial velocity) 0km hr
- Vertical circular motion minimum speed proof - Physics Forums
hi, i've read in a lot of places that the minimum speed fora body to "finish" a vertical circle is (rg)^0 5, but I've never understood why they assume the
- Relation Between Spring Constant and Angular Velocity
I was going through Periodic Motion chapter of my book and came across an equation while defining the relation between Time Period of on oscillating particle and force constant k m=w2 which was applied in, T = 2xpie angular velocity can anyone please help me define this equation I can't seem
- Problem in understanding instantaneous velocity - Physics Forums
The average velocity is the rate of change of position over a time interval, while the instantaneous velocity is the rate of change of position at a point in time As a time interval approaches a point in time, the average velocity approaches the instantaneous velocity
- Velocity of an Object Dropped from Height: Law Explained
an increase in the height from which an object is dropped positively correlates with the final velocity of the object as it falls It has more time to fall, so it will hit at a greater speed There isn't a law that states this, but it follows from the mechanics of constant acceleration You might want to note something about air resistance and terminal velocity
- Find Velocity given Force and Mass - Physics Forums
Velocity is the speed at which an object is moving It can also be thought of as the speed of a moving object divided by the time of travel In this case, it is the speed of a body divided by the time taken for the body to move a given distance
- Relative Velocity of Rain Drops in a Moving Vehicle
The velocity of the rain relative to the car is the difference between the velocity of the rain relative to the ground and the velocity of the car relative to the ground
